Probably not, at least not anytime soon. Not only have there been heavy hints that Caleb and Hanna (Ashley Benson) will reunite, but after the episode showrunner Marlene King tweeted that she "saw" the chemistry between Spencer and Caleb, "butPLLs don't steal each others boyfriends."
Marlene made a similar point in a recent interview with The Insider, saying that Spencer and Caleb have "amazing chemistry together" but are "just friends." She explained that the Liars' deeply felt friendships are "extremely important" to the show. "At its core, Pretty Little Liars is a coming of age story about these four friends."
So while there were definitely some sparks flying last night, it sounds like romance is not in the cards for Spencer and Caleb. We just hope to see some more friendship moments between them. With Spencer's brains and Caleb's street smarts, they could be a formidable pair.
